DEVICE FOR FACILITATING COPYING.

SPECIFICATION forming part of Letters Patent N o. 489,954., datedJanuary 17, 1893.

Application filed November 3, 1892. Serial No. 450.850. (No model.)

.To all whom t may concern:

Be it known that I, JOHN J. HILL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Devices for FacilitatingCopying, of which the following is a specification.

My invention relates to an improvement in the device for facilitatingthe operation of copying set forth in my application for Letters Patentof the United States Serial No. 437,516, filed on the 21st day of June,1892, and allowed on the 18th day of July, 1892.

My present improvementcontains the same principles of construction andoperation as that of my aforesaid application; butit is designed forbetter adaptation of the device as a reflecting copy-holder for use,particularly, by type-writing copyists.

To this end my invention consists,broadly, in providing the device,involving an openbase frame supporting a pair of reliectors occupyingrelative positions the one to reflect the copy on the other and thelatter again to reflect the reflection into the angle of vision of theuser, with a suitable feed for the copy, whereby the latter may bereadily adjusted, in copying, in the device to suit the convenience ofthe copyist with regard to the lines.

The invention also consists in details of construction and combinationsof parts, all

-as hereinafter set forth and claimed.

In the accompanying drawings, Figure l is a broken perspective view ofthe improved device, showing the feed in its preferred form; Fig. 2 is across-section of the same taken at the line 2 on Fig. l and viewed inthe direction of the arrow; Fig. 3 is a view of the device in endelevation showing a modication of the feed; Fig. 4 is a cross-sectionalview like that presented in Fig. 2, but showing another modification ofthe feed; and Fig. 5 is a broken bottom plan View of the device.

A is the frame composed of the end-pieces r, fr, shown in the form ofshoes and affording bearings for the ends of strips p and p carryingreflectors or mirrors B and B. The rear strip p, at least, should, asshown, for purposes of the relative adjustmentof the reflectors, andthat of the reflector B with the open base between the strips, bepivotally supported; and I form the strips preferably of sheet-metalwith their edges bent over those of the reflectors to retain them, butwith the ends of each, if both are pivotal, (as they may be) or of onlythe one p, if the other be immovable, open, to permit the reflector itcontains to be conveniently inserted and withdrawn lengthwise, as, say,in substituting a magnifying reflector for a mere mirror.

C is a base on which the frame A is supported, preferably by hinging itat one side, as at the heel-portions of the shoe-shaped end-pieces r,whereby it may be raised and lowered in adjusting the copy in place onthe feed hereinafter described.

The feed I illustrate for my purpose is a friction roller D journaled atopposite ends in the base C (and which roller may be of Wood or othersuitable material covered, ornot, with rubber) and protruding above theplane of the top of the base through a longitudinal opening 0 therein; aroller D', journaled in the ends fr of the reflector-frame A co-operateswith the feed-roller D, which is provided with a handle for turning it,shown in Fig. l as a milled wheel E, and which is housed in an eX-tension C of the base C and protrudes at a portion of its peripherythrough an opening 0c in the extension. To increase the resistance toturning the roller D I may provide a friction-plate or spring n to bearagainst one ofitsjournals. Toadjustthecopy,thehinged frame A, (which mayhave a spring m on its hinge-rod to tend to lower it) is raised and thecopy placed between the rollers D and D; and the weight of the hingedframe is sufficient to hold the paper between the rollers, whereby itmay be fed in either direction by turning the wheel E to actuate thefeed-roller.

In Fig. 3 I show the wheel F. as a ratchet and a spring lever F.supported on the adjacent end of the base C and carryingapivotalspringcontrolled dog E2 engaging the teeth of the ratchet wherebypressure on the end of the lever turns the Wheel, the extent of theturning by each stroke of the lever being regulated by an adjustablestop l, shown as a screw in the bearing Z under the free end of thelever.

The modification in Fig. 4t differs from that IOO presented in Fig. 3,in having the lever E eX- tending under, instead of over, the center ofthe ratchet E, With its dog E2 engaging the teeth from the rear side;and the lever is under the top of the base-extension C with a key E3extending upward through it.

The operation of my improvement will be understood to be the following:The frame A being raised on its hinge, the copy is adjusted to extendacross the base C and roller D when the hinged frame is lowered upon thecopy with the roller D bearing against it with the weight andspring-resistance of the frame. The reiector B is adjusted to such anangle with relation to a line (or more than one line) of the copy as toreflect it, through the open base of the frame, upon the reflector B',the position of Which is such as to again reflect the reflected matterto an angle convenient to the vision of the copyist. By turningtheroller D from time to time at its handle, the copy may be fed to bringsucceeding lines into desired position in the device to be refiectedinto the angle of vision of the user; and, as Will be seen, the devicethus serves as a line-indicator as well as a reflector. The wheel Eshown in Fig. l, Without the lever and dog attachment, and which affordsthe simplest form of handle for actuating the roller D, permits feedingof the copy in either direction (thus reversal of the feed, a functionwhich is obviously desirable); While the other forms of handle, with thelever and dog attachments, permit feeding in only one di-l 1. In adevice for facilitating the reading of copy, the combination of a framehaving an open base through which to expose the copy, a pair ofreflectors in the frame, occupying relative positions the one to refiectthe copy upon the other and the latter to again reiiect the reflectioninto the angle or" vision of the user, and a feed for the copy,substantially as described.

2. In a device for facilitating the reading of copy, the combination ofa frame having an open base through which to expose the copy, a pair ofreflectors in. the frame, occupying relative positions the one toreiiect the copy upon the other and the latter to again reflect thereflection into the angle of vision of the user, a base on which thesaid frame is supported, a feed-roller on said base having a suitablehandle for turning it, and a bearingroller in the frame to co-operatewith the feedroller, substantially as described.
